Why were JSR 236 [1] and JSR 237 [2] not included in the Java EE 6 specification [3], as originally planned [4]? It looks like there are plans to incorporate JSR 236 into the proposed Java EE 7 specification. What are the recommended alternatives for concurrency in Java EE until then?

Roberto Chinnici, the Java EE 6 spec lead, indicated in this tech cast [1] that JSR 236 and 237 did not make it into Java EE 6 due to "process issues," but indicated that it is high priority for Java EE 7.
